Concept: Saab 9-X BioHybrid

Combine a 1.4-liter, turbocharged, BioPower (flex-fuel) engine with a big battery and other electric bits and you've got a BioHybrid, according to Saab. Exterior highlights include a "shooting brake" profile (think short, two-door wagon) devoid of door handles and mirrors, plus a roof spoiler and underbody diffuser that extend rearward for improved aerodynamics at highway speeds. Inside, the cargo floor is lined with rubber carpeting that prevents cargo from sliding around. When the tailgate is opened, the floor slides out automatically and recessed aluminum bars rise from the "sticky" surface to promote easier loading.
